WASHING-MACHINE.

To all whom it may concern:

Be it known that I, VVILLiAM H. PRESTON, a citizen of the United States,and a resident of the borough of Brooklyn, city of New York, county andState of New York, have invented a certain new and useful Improvement inWashing-Machines, of which the following is a specification.

This invention relates to washing inachines more especially designed asan attachment for stationary and other forms of wash tubs, and in whichrelation it is to be used in connection with an ordinary form of washboard and serve to rub the clothes thereover, thus relieving the handsof this wearing operation.

To this end, the preferred embodiment of the invention, generallystated, consists of clamps which are rigidly connected together and havejournaled in them a cross shaft, to the outer ends of which are attachedlevers provided with handholds. The opposite ends of the leverspivotally suspend arms which are weighted at their free extremities andat which points the reduced ends of a rubbing, or washing roller, isjournaled. This roller is fluted, or corrugated, in the direction of itslength to intermesh with the corrugations of the wash board, and iscaused to travel downwardly over the same by the depression of thehand-holds; the roller and attached parts being automatically returnedto initial position under the influence of a sprlng.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side view of my improved appliance as attached to astationary wash tub, the latter being shown in cross section, and theattachment in full lines in an elevated position, and in a depressedposition in dotted lines. Fig. 2 is a plan of the attachment applied tothe tub; and Fig. 8 is a front elevation of the attachment.

More specifically described, the invention consists of two inverted Uvshaped clamps 5, which are rigidly connected together, as by the screwsshown in Fig. 1, by a cross bar 6, arranged at the front, and have theusual clamping screws 7 for securing the clamps to the incline frontboard of the tub; the sides of the clamps likewise inclining, as clearlyshown in Fig. 1, to bring the tops Specification of Letters Patent.

thereof into a substantially horizontal position.

The clamps are ribbed to insure strength and lightness and havejournaled in their uppermost portions a cross shaft 8, to the outer endsof which, at the outside of the clamps, are fixed levers 9 which arealso of ribbed construction and are formed, adjacent to the shaft 8,with ofiset hand-holds 10, the latter serving as means for operating theappliance as will be hereinafter apparent. The ends of the leversremoved from the shaft 8, pivotally support, on bolts or pins 11, ribbedarms 12, the free extremities of these arms being thickened to provideweights 13. Rigid with the weights 13 at the extremities of the arms 12,are bearing blocks in which are journaled the reduced ends of a roller14. This roller, which is the washing or rubbing element of theattachment, is made of any suitable material and is constructed withcorrugations in the direction of its length, of a form to intermesh withthe corrugations of a wash board, in connection with which the applianceis used, as shown in dotted outline in Fig. 1.

It is apparent from the construction, thus far described, upon graspingand depressing the hand-holds 10, the roller 14:, pressed by the weights13, will be caused to travel downwardly over the wash board to near thebottom of the tub where it will pick up a quantity of water and raise itover the garment which is on the board being washed, as the parts arereturned to initial position, and thus rub and scrub the garment similarto the action of hand work in rubbing clothes over the surface of thewash board.

For automatically returning the parts to an elevated position each timethey are depressed, there is provided a helical spring 15 having itsopposite ends respectively secured to the cross bar 6 and the crossshaft 8; the connection between these parts being preferably effected byblocks 16, each block having a round shouldered projection for receivingand securing one end of the spring. The oscillations of the levers 9,are limited in each direction by forming the flanges thereof, adjacentto the cross shaft 8, with square heads as shown in Fig. 1, whichcontact with angled corners of the clamps 5, when the washing roller iselevated to a convenient point, and which contact with the top of theclamps just before the weights 13 strike the rear side of the wash tub.

It is evident that various changes may be made in the details ofconstruction hereinbefore described without departing from the essentialcharacteristics of this invention, and I consider that I am entitled tosuch modifications as fall within a clear interpretation of the claimsannexed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A washing attachment for wash tubs comprisinginverted U shaped clamps adapt ed to be secured to the front of the tub,a cross bar rigidly connecting said clamps to gether, a cross shaftjournaled in the top of said clamps, levers fixed to the opposite endsof said shaft having ofiset hand-holds adjacent thereto, arms freelysuspended from the opposite ends of said levers having weightedextremities, a corrugated washing roller journaled in the weighted endsof said arms, and a spring connected to said cross bar and cross shaftoperating to elevate the levers, arms and roller when depressed by saidhand-holds.

2. A washing attachment for wash tubs comprising inverted U shapedclamps rigidly connected together and having angled corners, a crossshaft ournaled in the upper portions of said clamps, levers fixed to theopposite ends of said cross shaft having heads, arms pivotally suspendedfrom the opposite ends of said levers, a washing roller journaledbetween the free ends of said arms, said levers having hand-holds fordepressing said roller until the heads thereof contact with the clamps,and means for automatically elevating the roller, arms and levers untilthe said heads contact with the angled corners of the clamps. V

3. A washing attachment for wash tubs comprising clamping means, a crossshaft journaled in said clamping means, ribbed levers fixed to the outerends of said shaft, ribbed arms pivotally suspended from the oppositeends of said levers, a washing roller journaled between the free ends ofsaid arms, said levers having offset hand-holds for depressing thewashing roller, and a spring connectingthe clamping means and crossshaft for automatically returning the roller to an elevated positionwhen depressed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
